GRAIN-CAR DOOR Application filed August 23, 1929. Serial No. 388,002.

. same can be swung to stored position against the side wall of the car and is free when released to swing under the pressure of the grain into an open position substantially at right angles to the car and to arrange the general door structure so that it is not necessary to change the existing structure of the car in order to install the door.

A further object of the invention is to provide an all metal main door amply braced and to associate with the main door a metal upper door section, th latter section being also adapted to take a stored position against the wall of the car and swing outwardly to an open position substantially at right angles-to the car.

it further object to construct a hinged door having manually operated means at the i 1' the eof ior errectively releasably it to the adjacent post and to associ- 1 the door a leader a rich not only "e door but gives convenient approach '0 loci-1i" glever employed and to the upper door section for grain testing purpo A. further object of the invention i to no vide an adjustable guard plate against which the door can be closed and subsequently locked. the guard plate also 'assurinoof a 1 0 J. o 1 J.

l Vith the above more important and other minor objects in view which will become more apparent the description proceeds, the in yention consists essentially in the arrangein ut and construction of parts hereinafter more particularly described, reference being had to the accompanying drawings, in which 2-- l is an exterior view of the door as it appears in use and in the loclred position. a

In the drawings like characters of reference 56 indicate corresponding parts in the several figures.

We have not considered it necessary to show the complete body of the car in which tle for the purposes of thepresent disclosure to simply show the doorway opening bounded as usual bythe sill 1, lintel' or upper cross beam 2, door posts3 and 4, the inner lining boards 5 forming the interior wall of the car and the outer face boardsfi forming the outer wall of the car. r

The main door or lower section 7 is substantially rectangular and is an all metal one formed froin plate steel of good grade. The one edge of the plate is rolled to provide a vertical tube 8 adapted to receive a vertically disposed rod 9 which has the lower end thereof bearing in a threshold plate 10 secured to the car floor 11 and extending between the posts and the upper end thereof extended considerably above the door and received in a sleeve like hearing 12 formed at one end of a bearing plate 13 fastened to the interior wall of the car.

The rod and tube 8 form a pivot support for the "main door perinitting the same to be swung back against the interior face boards 5 of the car when not in use andas shown in Figure 3 and to be swung outwardly through the doorway opening into a position substantially at right an les to the side wall of the ear, the width of the door being such that the free end thereof will just nicely clear a vertically disposed locking bar 14 secured to the face ofthe door post 1-. The threshold plate has the opposite edges thereof tapered and it underlies the closed door and there is very little clearance space'between the lower edge of the door and the plate so that there is no possibility of grain leaking out at sue point. 7

The free end of the door is amply reinforced on'the outer side by a-vertically dis- 1 posed T-bar 15 spot welded thereto. This W can be made as shown or can be formed from two angle irons placed back to back. Centrally to the outer face of the door, we spot weld two vertically disposed spaced angle bars 16 and 17 which amply reinforce the body of the door and to the outturned flanges of the angle bars, we spot weld spaced cross rods 18, the angle irons and cro:s rods forming a ladder w rich permits one to easily approach the locking lever later described and also to take samples of grain from the car when desired.

On the outer face of the door, we mount a more or less vertically disposed locking lever l9 which is suitably pivoted to the door at 20 and the upper end of the lever operates over the inturned llange of a horizontally disposed reinforciin angle bar 21 spot welded to the door and extending between the angle iron 17 and the T-bar 15. The latter flange is provided with a notch 22 into which the end of tne lever escapes, it being understood that the lever is suiiiciently resilient to spring into the notch when the same is swung towards the same.

To the lower end of the lever, we pivotally connect a link 23 which is pivotally connected also centrally to a vertical bar 24 located adj acent the inner side of the inturned flange of the T-bar and the bar 24 carries upper and lower horizontally disposed locking bolts 25 and 25 which pass slidably through suitable openings 2. and 28 provided in the flange of the T-bar. In actual practice, when the up per end of the lever is swung to the right, the inner end of the link 23 will strike the bar 17 and limit the in travel of the bolts and when the bolts are in their inner positions, their outer ends are approximately flush with the outer face of the T-bar flange.

Means is provided for locking the lever when in the notch 22, such embodying a hook 29 permanently welded to the door and having the outer end adapted to overlie the lever when in the notch and at such time to pass irough a suitable opening provided in the ng 30 secured to the lever. The end of the 1 0k is supplied with a hole 31 adapted to reseal 32 of any approved design.

T-bar one a car .rhe lever is shown as locked by the seal bar 14 hereinbefore mentioned is provider at he inner edge with cross slots 33 and 84 adapted to receive the projected locking bolts 25 and 25 when the door in the closed position, the plate 14 and projected bolts preventing the opening of the door under pressure of the grain in the car. The adjacent portions of the door frame are also cut away as indicated at 35 to receive the projected bolts.

In the interior or" the car in a location joining the bar 14, we locate a vertically disposed guard plate 36 which is transversely slotted at 37 and 38 to receive the projecting ends of bolts 89 and 40 passed through the adjacent post 4, the inner screw threaded ends of the bolts being provided with winged nuts 41. and 42 preventing escapement of the plate 36. Between the latter plate and the wall of the car, we insert rubbing or wear plates 43 and 44, these being fastened to the wall and the guard late has the edge thereof towards the doorway opening slight ly curved as best shown in Figure 5 and the said plate is adapted to take a position to the inner side or" the door when the same is locked in closed position by the locking bolts.

By releasing the winged nuts, one can laterally shift the guard plate on the bolts and when withdrawn, it permits the door to be swung to closed position and when extended, it tar res a posi .on with the curved edge th reoit en aging the inner face of the door set shown 11. Figure 5 and here it will observed that the arrangement is such that hen the win ed nuts are tightened up, the curved edge of the plate is tightly pressed into contact with the rear face of the door to insure ot a tight grain proof contact. A

idle is sup-plied for manipulating the guard car b at shown in Figure 3 and in this position it can be releasably locked against swinging by a strap 46 secured to the wall of the car and adapted to receive the upper lecl bolt shown in said figure.

Above the main door section, we locate an auxiliary door 4'? which is made from a metal plate pivotally supported from the rod 9 in the same manner as the main door. The auxiliary door is supplied central y with a handle 48 and at the iiree end with a pivoted latch 49, the latch being adapted to engage a catch 50 secured to the wall board 5 and hold the auxiliary door in stored position as best shown in liigure 3. The length of the door 47 is such that it will close against the inner face of the opposing post 4 and in such position the latch is adapted to swing down and enter a suitable slot 51 provided. The lower edge 01" the auxiliary door laps the upper edge oi the outer door being to the inner side thereof when both doors are closed.

hen it is desired to close the main door, one can extend he plate 36 and fasten it by the winged nuts, then swing the door inwardly against the plate and then throw the upper end of the lever to the left to project the locking bolts into the slots 33 and 34. At this time the lug 30 will have received the hook and the car seal can be applied. The upper door section can obviously be closed by inging it into contact with the post 4 and then throwing down the latch to enter the slot 51.

When it is desired to unload the grain from the car, one breaks the seal and swings posts, said rod having the upper end of the lever to the right, at which time the main door will swing'outwardly under the pressureof the grain to a position substantially at right angles to the r' car and here we might point out that at such time the angle bar 16 is clear ofthe door frame. If it be desired at any time to take a sample of grain from the car, this can be done by releasing the upper door section.
